Specification of Letters Patent.

Application filed December 11, 1909.

To (ZZZ whom it may concern:

Be it known that I, CHARLES S. Bn'rnonr, a eitizenfof the United States, residing at Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Manual Start and Stop Motions, of which the following is a full, clear, and exact description. My invention relates to manual start and stop mechanism for machines, and is particularly concerned with mechanism of this 0 iaracter which is adapted for use in. combination with machines for handling a plurality of articles, such, for example, as the coin stacking and wrapping machine illustrated in my Patent No. 998,880, July 25, 1911. It is to be understood, however, that the mechanism may be, employed generally in conjunction with machines which are constructed to operate intermittently upon the passage of a coin or other article from a feed chute, or other conducting means, into the machine.

The object of the invention is to provide means for connecting the power shaft with the operative parts of the machine after the last article to be operated upon has passed from the feeding means into the machine, in order to enable the machine to perform its usual functions upon the last group or stack of articles so fed whenthe intermittent connection usually effected by the passage of the articles into the machine is interrupted, or has ceased.

The invention therefore contemplates broadly means for manually effecting the connection above described and the combination of such means with the means for effecting intermittent connection of the power shaft with the operative parts of the machine.

, With these objects in View, the invention consists in the construction and arrangement of parts, one embodiment of which is illustrated in the accompanying drawings.

Figure l is a plan View of so much of the power mechanism of the machine illus- 'trated in my co-pending application above referred to, as is necessary to illustrate the present invention and showing my invention in. conjunction therewith. Fig. 2 is a side elevation of so much of the coin advancing mechanism of said prior application as is necessary to illustrate the present invention in conjunction therewith. Fig. 3 is a plan view of the main features of the manual prises a power shaft 1 journaled in a bcaring 2 on a part 3 of the machine frame, said shaft carrying a pulley wheel l for connection with a suitable source of power. Also journaled in the machine frame is a shaft 5 carrying a worm gear 6 which is arranged to mesh with the worm gear 7, Figs. 5 and "7. which in turn is connected with the power shaft 1 by clutch mechanism hereinafter to be described.

Before entering upon a detailed description of the particular features in which. the

present invention resides, a. brief description of the ordinary intermittent. connection of the power shaft with the operating parts of the machine will be givenwith reference to the type of machine illustrated in my co-pending application. above referred to; It isto'be understood, however, that reference to said machine is made for illustrative purposes only and that the present invention may be employed in conjunction with machines of other types.

In Fig. 2 is illustrated a coin advancing mechanism similarin its general construc-.

tion to that illustrated in my co-pending application and comprising a standard 8 upon which is mounted an adjustable feed chute 9.by which the coins are directed into thepath of the several advancing elements. These elements comprisethe resscr 10. by which the coin is advanced from the feed chute into the path of the push bar 11, bv which it isthen advanced beneath the lift bar 12 to the coin stacking means, as fully described in the aforesaid application. The advance of each coin beneath the lift bar 12 raises the same and this movement is trans mitted by connecting rod 13 and crank arm 14 to a clutch operating shaft 15 extending transversely of the machine. Upon the opposite end of the clutch shaft 15 is a depending crank arm (not shown) to which is connected a horizontal sliding clutch-op crating push bar 16, whichinturn is jointed at 17 to a clutch operating member 18, slidably mounted in a casing 19 secured to the machine frame 8 and through which the power shaft 1 passes.

Referring particularly to Figs. 5, 6, and 7, the power shaft 1 has fixed thereto a. collar 20 having a single tooth 21, and upon this collar is loosely mounted the spiral gear 7, said gear having a recess 22 in which is pivotally mounted a pawl or clutch lever 23. adapted to engage and disengage the single tooth 21, as will be presently explained. Adjacent to the worm gear 7 the casing 19 has an annular channel 24:, said channel being adapted to receive a pin 25 projecting from the swinging pawl or clutch lever 23. The push bar 18 is actuated through the lift bar 12 and clutch shaft 15 each time a coin passes beneath said bar 12, by which said push bar 18 is reciprocated transversely of the channel 2% in the casing 19. The inner end of the push bar 18 is recessed at 26 to provide a lug 27 having an inclined wall 28. When no coin or other article is passing be: neath the lift bar 12,.the push bar 18 is retracted and the inclined wall 28 is withdrawn from register with the annular channel 24 in the caslng 19 and is in engagement wlth the pm 25 011 the swinging pawl 23 and holds said pawl out of range of action of the 1 beneath the lift bar 12, there is no longer any agent by which the intermittent connection of the power shaft with the operative parts of the machine can be efiected. i however, to complete the cycle of operations ,of the machine as a whole, upon the last stack of coins or articles which has been fed single tooth 21 of the fixed collar 20, thereby disconnecting the spiral gear 7 from the power shaft, but as each coin or other article passes beneath the lift bar 12, the push bar 18 is advanced and the inclined wall of the lug 27 is moved into register with the annular channel 2% and the pawl 23 is swung inward into engagement with the singletooth 21 of the collar 20. At the same time the pin 25 of said pawl enters the annular groove 24-, whereby the spiral gear 7 is connected to the power shaft land revolves with said shaft, the purpose being to have this gear make one complete revolution each time a coin or other article is advanced beneath the lift bar 12 and to come to rest again beforethe next coin or article is advanced. Immediately after the passage of the coin or other article beneath the lift bar 12, the latter drops,

thereby rocking the clutch shaft 15 and witha cam shaft which is connected with and drawing the clutch push bar ,18 -to-, the retracted position shown in Fig. 5,,whereby as the spiral gear 7 completes its cycle the pin 25 strikes the inclined wall 28 of the lug 27 and the swinging pawl is withdrawn from engagement with the single tooth 21 of the sleeve 20, thus disconnecting the spiral gear from the power shaft. In actual operation, and when the machine is running at high speed, and coins or other articles are being continuously fed, the make and break of this clutch connection is hardly perceptible but whatever the speed of the machine the spiral gear is ordinarily not operated except by the actual passage of a coin beneath the bar 12.

Therefore, in the normal operation of the machlne by feed of the coins or other articles the spiral gear is brought into operation only when a coin is being advanced and is allowed to make a complete rotation before the advance of another coin.

The foregoing serves as an effective clutch mechanism for connecting the spiral gear and the power shaft while coins or other articles are passing beneath the lift bar 12 and being deposited in a stack holder ready for further operations of the machine. Any other well known clutch mechanism may be substituted for the foregoing device without departing from the spirit of the invention, it being understood that under ordinary conditions of operation of the advancing coins or articles that the clutch shall operate to connect the spiral gear with the power only when the coins or articles are actually advanced beneath the lift bar 12, said gear remaining inoperative when the coins are not advanced, even though the advancing mechanism be in operation.

Having described the usual means for intermittently connecting the power shaft with the other operative parts of the machine, I will now describe the particular features in which the present invention resides.

When the last coin or article has passed In order to the machine, it is necessary that the power shaft be again connected with the operative parts of the machine to perform such functions independently of this intermittentconnection and to maintain such connection until the cycle of operations of the machine is completed. To this end I have devised a socalled manual start and stop mechanism which may be thrown into operation after t the aassa e of the last coin or article to the stacking or bunching mechanism, as described 1n my previousapplication.

Referring to Figs. 1, 3 and 4-, 29 1nd1 cates operated by the shaft 5 carrying the worm 1 gear 6 in any desired manner, as shown, for example, in my application above referred to. This shaft 29 is designed to make one complete revolution during one complete cycle of operation of the machine. I make use of this function therefore to maintain the clutch connection between the power shaft and the machine in operation for acorrespending period by the following means, On the shaft 29 is fixed a latch cam wheel '30 having an annular ledge 31, Fig. 3, on

one face intersected by a radial beveled rib 32, Fig. 4, said latch wheel preferably havledge 31 of said latch wheel. Said latch bar also is provided with a handle 40 for manual operation. The end of the latch bar 3et opposite the latch wheel is provided with a recess ll arranged to receive a lug 42 fixed to the clutch shaft and a stop pin4-3 on the machine frame is interposed in the path of said latch bar.

In the normal intermittent operation 0 the machine as above described, the latch 37 c mechanism of a second shaft, a clutch interposed between said shafts, a latch wheel on is withdrawn from the latch wheel and stands in retracted position, shown in Figs. 3 and 4. When, however, the last coin or article has passed beneath the lift bar 12, the latch bar 34: is pushed to the rear by the handle until the latch shoulder 39 engages within the ledge 31 on said latch wheel. It is to be understood that the connection of the cam shaft 29 with the power.

through its engagement with the lug 4L2 rocks the clutch shaft 15 and throws the clutch int-o operative position, as herebefore described, whereby rotation of the latch cam wheel 30 is started. As soon as the beveled rib 32 passes in such rotation beyond the latch 37 the latter snaps into position within the ledge 31 and automatically maintains the clutch in operation, and inasmuch as the latch cam wheel completes a rotation simultaneously with the completion of a cycle of operations of the machine, the clutch will under ordinary conditions be maintained in operation for an equal period of time. Just as the cycle of operations of the machine is completed, however, the beveled rib 32 engages the latch 37 and releases the same whereupon. the latch bar 34: is automatically retracted by the spring 34 and consequently the clutch is automatically thrown out of operation leaving the operative parts of the machine in position to begin a new cycle of operations.

Under ordinary conditions'when the machine is operated intermittently by the feed of coins or articles, the operation of the machine may be interrupted, should such course become necessary upon accident to the machine or otherwise, merely by checking the feed. Likewise should conditions so demand, the operation of the machine embodiment of my invention and a particular construction of latch bar and connecthrough the manual. start mechanism just described may be interrupted by manually releasing the latch bar 37 against the spring 38, whereby the operation of the machine may be stopped at anypoint desired during its cycle. i

While I have herein described a preferred tions thereof with the clutch mechanism, and have also described the invention in conncction with a particular type of machine, ;itis to be understood that the invention may be varied in details and relative arrangement of parts and may be applied to machines of various types without departing from the spirit and scope thereof.
